Unity Auto Setup

It’s the collider manager script, if Magica Cloth is enabled but only for the hair, it gets stuck in a loop looking for the cloth colliders.

If you enable Magica cloth physics as well as hair physics (even if there isn’t any cloth physics) it should fix it. Or you can just remove the Collider manager script from the prefab.

Thank you very much victor!

Did you mean these strands? Isn’t that CC doesn’t support alembic hair?
